Cognex DataMan DM8700 Scanner with Ignition TCP Driver - Connected but No Scan Data Received

Ignition
1

Hi everyone,

I'm working on a new Finished Goods scanning project and trying to integrate a Cognex DataMan DM8700LX-WF scanner with Ignition 8.1.

Current setup:

  • Scanner IP: 10.1.9.36

  • Scanner connected to WiFi network

  • Ignition device configured using the TCP Driver

  • Device status shows Connected (1/1)

  • OPC Browser shows: Device Name and last receive date, Message, MessageBytes

  • However:

    • Scanning a barcode does not update Last Receive Time
    • Message remains empty/0
    • MessageBytes remains empty/0
    • Test-NetConnection 10.1.9.36 -Port 23 returns TcpTestSucceeded : False

    The scanner is known to work and was tested successfully through Cognex DataMan Setup Tool on another workstation.

    My questions:

    1. Is the Ignition TCP Driver the correct approach for a DataMan DM8700 scanner?
    2. Does the scanner need to be configured as a TCP Client or TCP Server?
    3. Is there a standard Cognex port typically used for sending barcode reads?
    4. Has anyone successfully integrated a DM8700 directly with Ignition, and if so, what communication method was used?

    Any guidance would be appreciated. Thanks!

Normally you use the Cognex IP and the configured Telnet port. That is normally all I’ve had to do.
